Cocaine- and amphetamine-regulated transcript (CART) peptide (CART-(55-102)) is involved in the suppression of food intake. We now report that CART-(55-102) is involved in anxiety in rodents. Intracerebroventricularly administered CART-(55-102) as well as intraperitoneal administration of N-methyl-beta-carboline-3-carboxamide (FG-7142), a selective(More)
Receptor binding, behavioral, and electrophysiological profiles of 2-[N-(2-methylthio-4-isopropylphenyl)-N-ethylamino]-4-[4-(3-flu orophe nyl)-1,2,3,6-tetrahydropyridin-1-yl)-6-methylpyrimidine (CRA1000) and 2-[N-(2-bromo-4-isopropylphenyl)-N-ethylamino]-4-[4-(3-fluoropheny l)- 1,2,3,6-tetrahydropyridin-1-yl)-6-methylpyrimidine (CRA1001), putative novel and(More)
Alexander disease is a leukoencephalopathy that usually presents during infancy with developmental delay, macrocephaly and seizures. Several sequencing analyses have identified mutations in the gene encoding glial fibrillary acidic protein (GFAP) of patients with Alexander disease. We described a girl who developed seizures in infancy with atypical CT(More)
The aim of this study is to determine the efficacy of prophylactic treatment for patients with febrile convulsions (FCs) in whom electroencephalograms (EEGs) revealed epileptiform discharges. We retrospectively investigated 43 patients who met the following criteria: (a) at least one FC during the study period; (b) epileptiform discharges were first(More)
We investigated the effects of a novel melanocortin-4 (MC4) receptor antagonist,1-[(S)-2-(4-fluorophenyl)-2-(4-isopropylpiperadin-1-yl)ethyl]-4-[4-(2-methoxynaphthalen-1-yl)butyl]piperazine (MCL0129) on anxiety and depression in various rodent models. MCL0129 inhibited [(125)I][Nle(4)-D-Phe(7)]-alpha-melanocyte-stimulating hormone (alpha-MSH) binding to MC4(More)
Receptor binding and behavioral profiles of N-(4-chloro-2-phenoxyphenyl)-N-(2-isopropoxybenzyl)acetamide (DAA1097) and N-(2,5-dimethoxybenzyl)-N-(5-fluoro-2-phenoxyphenyl)acetamide (DAA1106), novel, selective agonists for the peripheral benzodiazepine receptor (PBR) were examined. DAA1097 and DAA1106 inhibited [3H]PK 11195 binding to crude mitochondrial(More)
Duchenne and Becker muscular dystrophies, generically called dystrophinopathy, are caused by mutations of the dystrophin gene. It is not surprising that mutations of the dystrophin gene cause various neurological symptoms, since dystrophin protein is found in the brain tissue as well as in the muscle fiber cell membrane. However, few studies have reported(More)
A 20-year-old woman with progressive leukoencephalopathy developed mental and motor disabilities and fell into a coma after suffering head trauma and febrile episodes from infancy. Brain imaging showed massive abnormal signals in the white matter. The electron spectroscopic imaging of biopsied brain tissue confirmed the electron-dense deposits to be(More)
We explored the possible role of the specific regions in the brain stem on the antinociceptive actions of mesaconitine (MA) and benzoylmesaconine (BM) by the microinjection of MA and BM into nucleus reticularis paragigantocellularis (NRPG), nucleus raphe magnus (NRM), and periaqueductal gray (PAG). MA microinjected into NRPG, NRM, or PAG elicited a(More)
The analgesia-producing mechanism of processed Aconiti tuber was examined using rodents whose nociceptive threshold was decreased by loading repeated cold stress (RCS). The antinociceptive effect of processed Aconiti tuber (0.3 g/kg, p.o.) in RCS-loaded mice was antagonized by pretreatment with a kappa-opioid antagonist, nor-binaltorphimine (10 mg/kg,(More)
